Road-Force balancing isn't the be-all end-all but if you are getting the tires balanced anyway (you are) and the shop has a Road-Force machine (they might) then you might as well get them balanced on the road-force machine from the get go. It "may" detect construction defects that are otherwise difficult to diagnose and are better dealt with before the tires have ever been on your vehicle. And you'll get a good balance.

If you have a lot of time on your hands (to read the tech) and want to really impress (or befuddle, maybe irritate) the shop techs, ask if they are using the Haweka Flange-plate adapters required by Toyota (for their dealers).
